Abstract
Background: Low adherence to antiretroviral treatment (ART) in people living with HIV (PLHIV) remains a critical issue, especially in vulnerable populations. Although ART is responsible for greatly reducing the mortality and morbidity associated with HIV, low treatment adherence continues to impact the effectiveness of ART. Considering that a high level of adherence to ART is required for the excellent clinical outcomes with which ART is often associated, understanding the complex contextual and personal factors that limit high levels of treatment adherence remains paramount. Poor adherence remains an issue in many South African communities many years after the introduction of ART.
Objectives: Our study sought to understand the specific factors and the interactions among them that contribute to non-adherence in this patient population in order to devise successful and contextually appropriate interventions to support ART adherence in PLHIV.
Methods: This mixed-methods study employed a study-specific questionnaire (N = 103) and semi-structured interviews (N = 8) to investigate the factors linked to non-adherence at the Heideveld Community Day Centre in Cape Town, South Africa.
Results: Over half (57.3%) of participants were ART non-adherent. Non-adherence was correlated with younger age, negative self-image and a low belief in the necessity of ART (P < 0.05). In patient interviews, alcohol use, treatment fatigue and stigmatisation emerged as contributors to suboptimal adherence.
Conclusion: The results suggest that there remains a need for context-sensitive interventions to support PLHIV in South African communities. Future research needs to ensure that these targeted interventions take these factors into consideration.
